A modular battery 100 for an electric work vehicle 300 includes first and second battery packs 110, 120. The first battery pack is configured to power the vehicle. The second battery pack is configured to power the vehicle and to power an auxiliary electric power tool 200 which may, or may not, be separate to the vehicle. The second battery pack is configured to be removable from the modular battery and comprises a DC-AC power converter (inverter) for powering the electric power tool. The second battery pack may comprise first, second and third states. In the first state, the second battery pack is mounted to the vehicle. In the second state, the second battery pack is dismounted from the vehicle to power the electric power tool. In the third state, the second battery is mounted to the vehicle and is electrically removed, or disconnected, from the modular battery to power the electric power tool, but not power the vehicle.
